HT-PVC Pipe, Fittings and Valves

High-temperature PVC for industrial hot water beyond standard PVC-U limits.

Standard PVC-U derates sharply above about 45 °C. HT-PVC is formulated to hold usable pressure at higher continuous temperatures, which makes it the option between ordinary PVC-U and CPVC on industrial hot water and cooling circuits.

Supplied as a system: pipe, fittings and valves in the same compound, because mixing a standard PVC fitting into an HT line reintroduces the temperature limit at the joint.
